Dissertations / Theses on the topic 'Resource adequacy'

For centuries, pandemic influenza has emerged at irregular and unpredictable intervals to cause widespread illness, hospitalization and death. Uncertainty surrounding the timing and severity of future influenza pandemics present challenges for preparedness and response efforts. The objective of this dissertation is to advance pandemic influenza knowledge and preparedness, through a series of interrelated articles that address the follow research questions: 1. What are the likely consequences of a pandemic flu event in Canada? 2. What do mathematical models tell us about preparing for such an event? 3. What is the best way to mitigate the consequences of an influenza pandemic? Six articles were prepared for submission in scientific, peer-reviewed journals. The first is a historical review of the burden of pandemic influenza. The second and third are systematic reviews of the effectiveness of interventions to interrupt pandemic influenza transmission. The fourth and fifth are research papers presenting a novel mathematical model, assessing the preparedness of the Canadian hospital system to accommodate expected surges in patient demand and evaluating intervention strategies to mitigate impact. The sixth is a policy-oriented paper discussing pandemic policy options within the context of public health ethics and risk management principles. Pandemic vaccination, antiviral treatment, voluntary isolation and personal protective measures were identified as the most cost-effective interventions available. Antiviral prophylaxis, community-contact reduction, school closure and quarantine were less effective, and tended to be associated with higher associated economic burdens. The timely implementation of layered intervention strategies appears likely to protect hospital-resource adequacy, though areas of Southwestern Ontario appear to be more vulnerable to surges in patient demand. However, the potential for high health and economic burdens, coupled with the uncertain severity of future pandemics, necessitates a flexibility in preparedness and response plans.

The primary purpose of this research is to explore the relationships between Beer's viable system model (VSM) and mainstream functionalist organisation theory.The latter is taken to include the classical, behavioural and systems models of organisation. For completeness, we also consider organisation theory situated in the interpretive, radical humanist and radical structuralist paradigms of Burrell and Morgan's (1979) sociological grid. Models of mainstream organisation theory have been used extensively by organisation theorists in the structuring of organisations and the design of information systems. Little interest, however, has been paid by organisation theorists to Beer's VSM, which is also used by cyberneticians to structure organisations and design information systems. The problem is that both camps have developed in isolation from one another. Theorists in each camp advocate their own stance regardless what the other might have to offer to their thinking. This situation is a result of a gap between the two camps owing to lack of dialogue between them. The aim of this thesis is to attempt to bridge the gap between the two camps. It is the author's firm belief that this is best done by adopting a complementary approach to pinpoint domains of support each camp may offer to the other. The outcome of this approach is an enhanced model of organisation. Part One of the research begins by introducing the science of cybernetics. Its history, tools, techniques and concepts are then put in place. Building on cybernetic tools and techniques, Beer developed a model of any viable system. Beer's VSM is presented in Chapter 2. Part Two of the thesis is totally devoted to organisational theory. First, we take up models of the functionalist mainstream organisation theory. The approach adopted is first to elaborate on each model, then to contrast each with the VSM. Attention is then directed to organisation theory located in the alternative paradigms, that is, the interpretive, radical humanist and radical structuralist paradigms, respectively. Again, theory of organisation within the above mentioned paradigms is contrasted with the VSM. We mark the end of Part Two by presenting an enhanced model of organisation. This model is the outcome of the comparison which took place between the functionalist organisation theory and the VSM. The argument is that the likelihood of the classical model providing support to the VSM is slim. In fact, the former stands to gain much from the VSM, particularly from the notion of recursive structures which explains how control and communication systems must be designed and organised. The behavioural model, which takes the informal aspects of organisation as its core, appears to be a useful adjunct to the VSM, which concentrates primarily on the formal organisation. Again, the behavioural model stands to gain much from the insights offered by the VSM. At least, the view of openness to the environment would surely give the behavioural model a boost in the right direction. However, we focus our interest on the systems model of organisation, specifically, the notion of semiautonomous work groups encapsulated in the sociotechnical systems approach. By incorporating this notion into the VSM we can, it is hoped, enhance the VSM. Once again, the insights of the VSM, especially that of recursivity of its structure, is of immense significance. In Part Three, the enhanced model is put to the test. This is done by applying it to an existing pharmaceutical manufacturer. The model proves to be not only practical, but also powerful in highlighting domains requiring attention if the effectiveness and efficiency of the organisation in concern is to improve, which the VSM, on its own, cannot provide.

Hotel guests can use 2 to 3 times more water than community residents. Hotels are water-intensive businesses, and water scarcity presents a pressing problem for managers who rely on an uninterrupted supply of water to meet guests' needs and maintain profitability. Using the resource-based view (RBV) as a conceptual framework, the purpose of this qualitative multiple case study was to explore strategies that hotel managers used to successfully maintain adequate water supplies in the Spanish Canary Islands, an historically arid site and a tourism destination. Data were collected from semistructured interviews and hotel water usage reports. Yin's 5-step approach of examining, categorizing, tabulating, testing, and recombining evidence to draw conclusions guided the data analysis. Four key themes emerged from the findings: value water as a strategic business resource, mitigate risks of natural resources scarcity, promote water efficiency and conservation, and sustain supplies through corporate water stewardship. This study may contribute to positive social change by illuminating processes that hotel managers, employees, guests, and partners, can take to improve environmental stewardship and align their practices with sustainable water governance.

<p>At a meeting of worl leaders at the United Nations Conference on Environment and Development in Rio de Janeiro in 1992, it was recognized that because of the tremendous increase in the size of the global populations (which now is estimated to exceed six billion), there were concerns that global biodiversity was at risk if insufficient land were not put aside for conservation within formal Protected Areas. The primary aim of this study was to compare investment in Protected Areas in relation to socio-economic conditions at global and regional levels.</p>

The theoretical part of this thesis describes the development of Czech banking sector, especially with emphasis on post-revolutionary rebirth within the new conditions of market economy. The following part demonstrates the decision-making credit account process of a bank on a particular case study based on the methodics and procedures leading up to maximal elimination of credit risk. At the same time, the author presents a partially modified internal opinion on a decision of particular business transaction. It is accented that every decision of a bank must comply with the regulations of CNB. The conclusion of the thesis affirms the maximal efforts of domestic banks to minimalize risks within their decision-making credit account processes, which is mirrored in current stability in the development of Czech banking sector.

Deregulation of the electricity industry has altered the investment landscape for new resources. Multiple resource adequacy constructs are in use today around the world and represent diverging opinions of how much interaction regulators should have on the procurement of new resources. The report compares the resource adequacy constructs in Australia, Texas, California and the Northeast of the United States and discusses the future of resource adequacy. The report concludes that a hybridized construct that blends the high offer caps of energy-only markets, the prescriptive nature of resources in capacity markets and a strong price-responsive demand will likely be the future of resource adequacy.<br>text

Renewable energy sources have received increasing attention in electric power systems around the world due to growing environmental concerns. Wind and solar are among the most promising alternatives to conventional energy generation. There has been a rapid growth of wind and solar energy integration in power systems in the last decade, and is expected to grow further in the years to come. The main concern with wind and solar energy sources is the uncertainty and the intermittency of power generation, which leads to problems in maintaining the overall system reliability. The impacts of these sources on bulk system reliability depend on a large number of factors. The strength of the wind or solar resource at the installation site, the existing renewable power penetration level in the system, the points of connection of these sources to the power grid, the correlation in resource availability between multiple installation sites, and the correlation between the load and the renewable power are key factors that are analyzed in this thesis. These factors are considered in evaluating the bulk system reliability and reliability benefits of wind and solar power sources, and the reliability worth to the electricity customers from the addition of these energy sources. The IEEE-RTS test system is utilized throughout the thesis to evaluate the effects of these factors on bulk system adequacy. Swift Current and Saskatoon wind resources are modeled and utilized in this thesis. The Swift Current area has a strong wind resource and provides better reliability benefit and reliability worth than the Saskatoon wind resource. The benefits from wind and solar power integration, however, also depend significantly on the location where it is connected to the grid network. Wind farms that are diversified in multiple regions with independent wind speed profiles provide superior reliability benefits and worth than wind farms located in one region. The incremental benefits of adding wind or solar power decreases as the renewable power penetration is increased in the power system. Wind power at practical locations provides higher reliability benefits than photovoltaics. However, the daytime contribution of photovoltaics to system reliability is relatively high. The reliability benefits and reliability worth of solar power are significantly different for different seasons. A comparison study on reliability benefit and worth between a wind integrated bulk system and a solar integrated bulk system is also done in this thesis in order to identify the best option for bulk system reliability.

A sample of 2,435 Canadian pre-retirement women aged 45 to 64 from Statistics Canada’s 2007 General Social Survey was used to examine the effect of sources of financial advice and information, controlling for 7 demographic and socioeconomic factors. The results of logistic regression indicated that levels of income, being in a relationship, having a better state of subjective health, and being born in Canada, were positively associated with women’s perceived adequacy of financial resources for retirement. Retirement planning experts, financial institution employees, accountants, partners, and employers were the key sources of financial advice and information that increased women’s perceived financial security for retirement. The results of this research can be used to better understand who among pre-retirement women are more or less likely to perceive their financial resources for retirement as adequate and whether the use of financial advice and information affects their perceived adequacy of financial resources for retirement.

A thesis submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. University of the Witwatersrand, Johannesburg<br>Power system adequacy has been historically insufficient in the Southern African Power Pool (SAPP) region with resulting negative effects on economic growth and electrification efforts. Existing domestic regulatory frameworks and opaque longterm bilateral contracting for procuring capacity in the region have been shown to be insufficient in ensuring system adequacy. The concept of an adequacy product in the form of a Capacity Mechanism (CM) introduced into the SAPP region has not yet appeared in the literature. A Capacity Mechanism (CM) for the SAPP region has been proposed and designed as part of this research to address this. A framework has been developed to consider CMs via the combination of a screening assessment, quantitative (model-based) analysis of more favourable CM options and an identification and quantification of key design elements. The developed framework can also be generalised and applied to other jurisdictions where CMs are under consideration. A regional CM which transparently and explicitly values capacity is proposed in the form of a forward-looking annual Capacity Auction that is locationally disaggregated, supplied by all possible supply-side resources with all feasible SAPP market participants included. The CM should be technology agnostic and account for the dual requirement for firm capacity to meet peak demand and firm-energy to meet annual energy requirements considering the dominance of hydrobased capacity in the region when excluding South Africa. There should be a leadtime of 3-4 years with the possibility of long-term auctions for large hydro-based capacity. Strict market monitoring and adherence to performance incentives and penalties will need to be ensured to avoid exercising of market power considering the dominant size of the South African power system. Appropriately mandated institutions to run Capacity Auctions would include the SAPP Co-Ordination Centre as well as a sufficiently mandated regional regulatory body. A further contribution is made in the form of a public domain power system dataset of the SAPP region with sufficient detail to be used in power system operations and planning efforts by future researchers and practitioners.<br>E.K. 2020

碩士<br>國立臺灣大學<br>會計與管理決策組<br>94<br>Credit Guarantee System is always an important system for each government to financially support so called“marginal business”. In our country, Small and Medium Business Credit Guarantee Fund (SMEG) was set up in June 1974, and till the end of 2001 (that’s almost 27 years), the Credit Guarantee Utilization Ratio (CGUR) in financial institution had been maintained at 6% or so. However, this ratio in April 2006 was boomed to 18.43%, 2 times increase. In contrast, during the same time, the loan of total financial institutions to SMEs was declining. Is the function of correcting the market-failure of credit guarantee system unavailable? This research mainly referred to the related function and organizations in Japan and Korea which are currently among the best practices of Credit Guarantee System all over the world, and also proposed ways of improvement in the Credit Guarantee Systems, considering the special economic circumstance of Taiwan. This research also suggested how SMEG could continually fulfill its public mission under information asymmetry, increasing ratio of non-performing loans, and the decreasing capital fund contributed from the government.

This study is concerned with the availability and adequacy of environmental information resources to support field workers at the Wildlife and Environment Society of South Africa's (WESSA) four environmental education centres in KwaZulu-Natal. It begins by examining the environment, the environmental crisis and environmental education as a response to the crisis, before giving an overview of the history of WESSA. To provide a wider context within which to view the study, literature dealing with environmental education, environmental education centres in South Africa and environmental information was examined. A study population consisting of 18 field workers and eight management staff, based at the four environmental education centres, was surveyed by means of interviews. This allowed for selected attributes such as length of employment at the centre, highest education qualification and previous environmental education experience to be elicited from field workers. Other information asked ofthe population concerned available environmental information resources, the environmental information support required by field workers and the adequacy of this support to field workers. Results were then analysed. With the responses to the open-ended questions, content analysis was used to determine categories which were subsequently tabulated, together with the responses from closed questions. The results revealed that WESSA provides a number of ongoing, in-house training opportunities which expose field workers to environmental information resources; WESSA publications dominate the environmental information resources used during the training offield workers and consequently, during the preparation and conducting of courses by field workers; booklets, books and colleagues are considered valuable information resources by field workers; and there is a recognised lack of environmental information by both field workers and management staff. Recommendations for improving the environmental information resource support to field workers are made in light of the results of the survey and the literature review.<br>Thesis (M.I.S.)-University of Natal, Pietermaritzburg, 2000.

A insegurança alimentar e o desperdício de alimentos são abordados pelos Objetivos de Desenvolvimento Sustentável (ODS) da atual Agenda 2030, desenvolvidos pelos países membros das Nações Unidas (ONU). Cada um dos estados-membros da ONU promoveu planos, programas, estratégias e / ou legislações aprovadas, destinados a lidar com o desperdício e a perda de alimentos (DPA) ao mesmo tempo em que alcançam os objetivos de todos os ODS. Essas participações efetivas são descritas por cada país num Relatório Nacional voluntário divulgado pela ONU na sua Plataforma de Conhecimento de Objetivos de Desenvolvimento Sustentável. Para ajudar a União Europeia (UE) a alcançar os ODS, a UE desenvolveu uma estratégia para reduzir o desperdício e a perda de alimentos, uma vez que a redução de DPA pode também: 1) lutar contra as alterações climáticas, através da redução das emissões de gases com efeito de estufa (GEE); 2) ajudar na erradicação da fome e da desnutrição, por meio da redistribuição dos alimentos resgatados; 3) gerar poupança económica para produtores e distribuidores; 4) ter impactos sociais positivos na vida das populações empobrecidas; 5) fortalecer os sistemas alimentares. Esta estratégia, denominada Estratégia Farm to Fork, apresenta uma série de ações que visam uma transição mais rápida para um sistema alimentar sustentável a qual deve ter um impacto ambiental neutro ou positivo, reverter a perda de biodiversidade, ajudar a mitigar as mudanças climáticas, garantir a segurança alimentar, nutrição e saúde pública, e preservar a acessibilidade dos alimentos. As políticas da UE com relação ao DPA são postas em prática pelos membros da UE aprovando leis ou implementando outras iniciativas para prevenir, reciclar ou reutilizar o DPA. Em Portugal, para promover a redução do desperdício alimentar através de uma abordagem integrada e multidisciplinar, a Presidência do Conselho de Ministros instituiu a Comissão Nacional de Combate ao Desperdício Alimentar (CNCDA). Um dos objetivos da Comissão Nacional de Combate ao Desperdício Alimentar (CNCDA) é identificar, avaliar e monitorizar as necessidades de adaptação da Estratégia Nacional de Combate ao Desperdício Alimentar (ENCDA) e do Plano de Ação de Combate ao Desperdício Alimentar (PACDA), apresentando relatórios periódicos ao Ministro da Agricultura. Depois de promover um inquérito às partes interessadas ao longo da cadeia alimentar, durante o 3º trimestre de 2020, o CNCDA concluiu que, exceto no canal HORECA: 1) houve um aumento nas doações / excedentes de alimentos resgatados, embora o canal HORECA não tenha seguido esta tendência global; 2) em todos os setores de atividade, a perceção geral era de que a pandemia COVID-19 tinha contribuído para a redução do desperdício de alimentos. Em simultâneo com as políticas internacionais e nacionais, os movimentos civis surgiram com o foco no combate ao desperdício, em todas as suas dimensões, da produção ao consumo. Esses movimentos têm como objetivo unir várias partes interessadas em uma luta ativa contra o desperdício de alimentos usando abordagens e possibilidades inovadoras. Uma das abordagens para combater a insegurança alimentar das famílias de baixos rendimentos, consiste em organizações de ajuda alimentar que resgatem e redistribuem os excedentes alimentares, do canal HORECA e do setor de distribuição. Como resultado, a adequação dos alimentos ou refeições distribuídas por cantinas sociais, mercearias solidárias ou bancos de alimentos têm sido objeto de investigação científica em diversos países. No entanto, os alimentos fornecidos nas organizações estudadas são, principalmente, ou adquiridos pela organização ou adquiridos por doadores que posteriormente doam esses alimentos à organização, ou ainda, em quantidades menores, resultantes de sobras de alimentos. Nessas organizações, devido ao seu custo e às necessidades de logística de transporte e refrigeração, os alimentos frescos costumavam ser fornecidos em quantidades baixas ou muito baixas. Como resultado, o teor de nutrientes das refeições e cestas de alimentos geralmente carece de vitaminas e minerais. Além disso, os resíduos alimentares sendo um reservatório de hidratos de carbono, proteínas, lípidos e outros macro e micronutrientes orgânicos e inorgânicos, podem ser considerados como uma fonte material na indústria de alimentos, indústria de ração animal ou indústria farmacêutica como aromatizantes e fragrâncias, antioxidantes, aditivos e suplementos alimentares. No entanto, como os processos de extração industrial exigem know-how e consomem mais tempo, materiais, energia e recursos humanos, a maneira mais favorável do ponto de vista ambiental de aumentar o ciclo de alimentos é usá-los como estão, para alimentar a população em insegurança alimentar. Tanto quanto sabemos, nenhuma outra investigação mediu e avaliou a contribuição de alimentos frescos ou preparados na hora, para uma dieta equilibrada de famílias de baixos rendimentos. Assim, nesta tese de doutoramento, pretendeu-se explorar as formas como o desperdício de alimentos é reciclado, focando principalmente no processo que leva ao consumo humano, medindo seus resultados no que diz respeito à quantidade de micro e micronutrientes reaproveitados, para a contribuição para uma alimentação equilibrada, para o alívio da insegurança alimentar e, finalmente, para a contribuição para o alcance dos ODS. Com base na lacuna de investigação identificada acima, esta tese é regida por quatro questões investigativas principais: a) Com é que o desperdício de alimentar está a ser reutilizado? b) Como é que os alimentos reciclados podem contribuir para a dieta equilibrada de famílias de baixos rendimentos? c) Qual é o conteúdo nutricional dos alimentos resgatados e redistribuídos veiculados por uma organização de ajuda alimentar, em relação aos valores de doses diárias recomendadas? d) Como é que o processo de reciclagem e redistribuição de alimentos pode contribuir para o cumprimento dos ODS? Derivando destas questões, foram estabelecidos seis objetivos principais de pesquisa: i) Fornecer uma atualização sobre o que foi encontrado para aumentar a reutilização do desperdício alimentar como um material ou fonte de energia, mas também para encontrar soluções de uso de desperdícios alimentares para consumo humano. ii) Avaliar o contributo dos alimentos frescos ou acabados de confecionar, resgatados e redistribuídos como complemento da alimentação das famílias de baixos rendimentos, de acordo como guia alimentar português (Roda dos Alimentos), utilizando a organização Refood-Leiria como estudo de caso. Esta avaliação é feita, em primeiro lugar, apenas considerando os dados categorizados como alimentos redistribuídos pertencentes à Roda dos Alimentos Portuguesa. Em segundo lugar, são considerados os dados totais, pertencentes ou não à Roda dos Alimentos Portuguesa, o que permite também a terceira avaliação, que consiste em comparar os alimentos reciclados, na organização do estudo de caso, com o padrão alimentar da população portuguesa em geral. iii) Quantificar os nutrientes dos alimentos resgatados e redistribuídos na organização do estudo de caso. iv) Avaliar como esses nutrientes contribuem para aliviar a insegurança alimentar das famílias beneficiárias. v) Avaliar as formas pelas quais o processo de reaproveitamento de alimentos frescos pode contribuir para o alcance dos ODS. vi) Propor uma estratégia para tornar o processo de resgate e redistribuição de alimentos uma atividade perene, naturalmente integrada na vida dos cidadãos. O projeto de investigação escolhido leva naturalmente a um desenvolvimento de pesquisa sequencial. A questão-chave inicial no início desta pesquisa foi “O que está a ser feito para melhorar a reutilização dos alimentos, principalmente para consumo humano?”. Após pesquisa exploratória da literatura, realizou-se a reflexão crítica, identificou-se uma possível organização do estudo de caso, foram estabelecidas questões de pesquisa mais específicas e consequentes objetivos iniciais. Além disso, um projeto à escala de uma tese de doutoramento requer constante aperfeiçoamento e adaptação. Assim, num processo iterativo, os objetivos iniciais i), ii) e iii) foram expandidos para iv), v) e vi). Em termos de materiais, novamente num processo iterativo, paralelamente à constante pesquisa bibliográfica, foram solicitadas autorizações, na organização do estudo de caso, para recolha de dados relativos aos alimentos redistribuídos e dados sociodemográficos. Foram pesquisadas e selecionadas ferramentas adequadas para avaliar o conteúdo nutricional dos alimentos redistribuídos e sua adequação, bem como valores de referência nutricional e guias alimentares. Para medir a insegurança alimentar, foi selecionada a Escala de Experiência em Insegurança Alimentar (FIES). Os programas utilizados na análise e tratamento dos dados foram o Food Processor Plus® (ESHA Research, Salem, Oregon), Microsoft Excel Office® 365 e IBM® SPSS® Statistics versão 27 para Windows®. Esta tese tem um formato cumulativo e baseia-se em três publicações científicas com revisão por pares, resultantes das diferentes fases da investigação. As publicações foram organizadas em três partes principais. A Parte I é baseada no capítulo do livro “Rerouting Food Waste for Climate Change adaptation: the paths of research”, apresentado no 4th World Symposium on Climate Change Adaptation WSCCA- 2021), que decorreu em paralelo com a COP26 em Glasgow, Scotland, a 3 de novembro de 2021, e aceite como capítulo do livro 4th World Symposium on Climate Change Adaptation Book - “Climate Change Strategies: handling the challenges of adapting to a changing climate”, a publicar na editora Springer. Fornece uma compilação de como a investigação para a reutilização de DPA tem evoluído desde a crise económica de 2008, para encontrar soluções inovadoras de uso de DPA tanto como fonte de biomateriais e bioenergia, como para consumo humano para combater a insegurança alimentar. Os resultados são discutidos sob as seguintes perspetivas: distribuição geográfica da instituição do autor, categorias temáticas e palavras-chave dos autores. Foram identificadas as tendências atuais e previsíveis na gestão de resíduos alimentares como matéria-prima e para a segurança alimentar. Verifica-se que os campos de interesse da pesquisa de DPA têm sido, por um lado, o desperdício alimentar como fonte de matériaprima para a produção dos biocombustíveis e dos biomateriais e, por outro lado, a reciclagem dos resíduos alimentares para consumo humano, como solução para a insegurança alimentar. A Parte II é baseada no artigo “The Contribution of Up-Cycled Food Waste to a Balanced Diet of Low-Income Households” publicado na revista Sustainability (2021), 13 (9): 4779. https://doi.org/10.3390/su13094779 e compreende a avaliação da contribuição de alimentos frescos ou recém confecionados, resgatados e redistribuídos para complementar a dieta familiar de baixo rendimento, de acordo com o guia alimentar português (Roda dos Alimentos), tendo como estudo de caso a organização Refood-Leiria. Em primeiro lugar, apenas são considerados os dados categorizados como alimentos redistribuídos pertencentes à Roda Alimentar Portuguesa. Em segundo lugar, são tidos em consideração os dados totais, pertencentes ou não à Roda dos Alimentos Portuguesa, o que permitirá também a terceira avaliação que consiste na comparação dos dados recolhidos, relativos a alimentos resgatados e redistribuídos, com o padrão alimentar da população portuguesa em geral. Os resultados sugerem que os alimentos reciclados podem contribuir para uma alimentação mais equilibrada em termos de “Batata, Cereais e Produtos de Cereais”, “Legumes”, “Carne, Peixe, Marisco e Ovos” e “Frutas”, ambos de acordo com a Roda Alimentar Portuguesa e em comparação com a população portuguesa em geral. A Parte III é baseada no artigo “The Nutritional Content of Rescued Food Conveyed by a Food Aid Organization”, publicado na revista International Journal of Environmental Research and Public Health (2021), 18(22):12212. https://doi.org/10.3390/ijerph182212212. Concentra-se na determinação do conteúdo nutricional de cestas de alimentos fornecidos pela nossa organização de estudo de caso. Todos os itens de cestas de alimentos são pesados, em três rodadas de pesagem durante um período de quatro meses. A Escala de Experiência de Insegurança Alimentar (FIES) foi aplicada para medir a insegurança alimentar das famílias. Os resultados mostraram que, no nosso estudo de caso de organização de ajuda alimentar, as doações de alimentos contribuem substancialmente para a ingestão da Dose Diária Recomendada (DDR) de energia, macro e micronutrientes. Ao avaliar como esses nutrientes contribuem para aliviar a insegurança alimentar das famílias beneficiárias, concluímos que a perceção de insegurança alimentar é independente da quantidade de nutrientes servidos. Tanto quanto sabemos, este é o primeiro estudo que mede o conteúdo nutricional de alimentos resgatados frescos ou recém confecionados, redistribuídos por uma organização de ajuda alimentar. Essas três partes são acompanhadas de um capítulo anterior, uma introdução geral à tese, e um último capítulo sobre as reflexões e conclusões finais em que as questões de pesquisa são respondidas. Limitações do estudo, bem como uma perspetiva sobre futuras investigações estão incluídas no último capítulo desta tese, seguidas pela bibliografia compilando todas as fontes citadas de todos os capítulos. Ao final da tese, são fornecidos dois apêndices, nos quais estão organizados todos os materiais de pesquisa relevantes, como os diagramas metodológicos da Parte II e da Parte III, Escala de Insegurança Alimentar em Língua Inglesa e Língua Portuguesa. O Apêndice B contém o diagrama da metodologia usado na parte II, e o Apêndice C contém todos os materiais usados na parte III.<br>There has been a growing concern in food waste and food loss reduction while the number of food insecure families in the European Union has increased resulting in an increasing number of households depending on food assistance programs. The practice of up-cycling food to improve the diet of low-income households not only tackles food wastage and food insecurity, but also has the potential to contribute to the fulfilment of other Sustainable Development Goals (SDG) (SDG 2 and SDG 12, as well as the potential to contribute to the fulfilment of other SDG, such as SDG 1, SDG 3, SDG 10, and SDG 13). After having conducted a scientific literature compilation in the food waste reuse field adopting a methodology based on the use selected key words, extracted results were divided in two categories: raw material and food security. Actual and predictable trends on food waste management were identified for both categories: food waste is regarded as a source of raw materials to produce biofuels and high value biomaterials, or as a solution to food insecurity through food aid organizations. However, there has been an increasing concern with the adequacy of food provided by these organizations, whether up cycled or not, due a lack a fresh food. Therefore, we endeavoured in a pilot study concerning the contribution of up-cycled fresh food to vulnerable households. This study analyses the contribution to a balanced diet of an upcycling food organization which rescues and redistributes fresh or freshly cooked food to low-income households, to determine the nutritional balance of food hampers provided by our case study organization, according to the Portuguese food guidelines. We also evaluate the ways in which the process of upcycling fresh food can contribute to achieve SDG. We determine the nutritional content of food hampers provided by our case study organization, weighing all items of food hampers in three weighing rounds over a period of four months. To evaluate how these nutrients contribute to alleviate food insecurity of the beneficiary households, the Food Insecurity Experience Scale (FIES) was applied to measure households´ food insecurity. In the conclusion we propose a strategy to make the food rescue and redistribution process a perennial activity, naturally integrated into citizens´ lives.

Orientação: João Pedro da Cruz Fernandes Thomaz<br>O terceiro Setor ocupa um lugar central na governação, na generalidade das sociedades contemporâneas. As novas exigências de competitividade, impõem também às Misericórdias, uma reestruturação dos processos de gestão, de forma a ser possível alinhar a missão organizacional com o nível de desempenho esperado. Pretende-se identificar um modelo de avaliação do desempenho dos colaboradores da Santa Casa da Misericórdia da Marinha Grande, que permita adequar o desempenho individual, às exigências funcionais e da Instituição. Foi adotada como base científica, a Metodologia Multicritério de Apoio à Decisão (MMAD), com vista ao alcance de uma maior à transparência e clareza das avaliações, e ainda, à obtenção de dados que permitam uma melhorada gestão do desempenho (relação dos resultados da avaliação, com as politicas de recrutamento, seleção e formação), gerando assim um modelo, em que todos possam confiar; O autor deste estudo pretende extrapolar o modelo identificado, a outras Misericórdias do País.<br>The 3rd Sector occupies a central place in the governance, of most contemporary societies. The new requirements of competitiveness also impose on the Misericórdias, a restructuring of management process in order to be able to align the organizational mission with the level of performance expected. The aim is to identify a model to evaluate the performance of employees of the Santa Casa da Misericórdia of Marinha Grande, enabling adjustments to individual performance to meet the functional and institutional requirements. The Methodology Multiple Criteria Decision-Aid (MMDA), was adopted as a scientific basis, with a view to achieving greater transparency and clarity of assessments, and also to obtain data allowing an improved performance management (ratio of assessment results with the policies of recruitment, selection and training), thereby generating a model in which everyone can trust; The author of this study pretends to extrapolate the identified model, to other Misericórdias of the country.

The post-apartheid government of 1994 is a product of the ‘Age of Rights’. Statemaking processes and the exercise of state powers is managed by the rule of law based on a constitution. Constitutionally recognised rights, and rights protection institutions, animate a transition from a legacy of Black political exclusion and underdevelopment. Intensifying class stratification and inequality constrain Black’s formal realisation of citizenship rights, placing great pressure on creative interpretation of constitutionally legitimated claims. My thesis examines the rights discourse informing the Constitution, particularly issues about the realisation of social and economic rights. I examine the unfolding of discourses on the right to housing between 1994 to 2008, to illustrate of the complexity of the discourse. Episodic housing protests suggest significant degrees of alienation, marginalisation, and disappointment with expectations of citizenship and the non-realisation of social and economic rights. Housing rights is an issue that will affect the democratic consolidation and political stability prospects of the new political order. I examine the interface between macro-economic policies, budgets, and the realisation of housing rights, and assess the impact of an identifiable configuration of forces expected to play important roles in realising a rights culture and broadening the discourse. My study draws on a spectrum of qualitative, interpretive, and analysis of discourse approaches, using data from: published articles, annual reports and archives, speeches, court proceedings and statements, interviews with persons whose scope of activities impact the unfolding of the concerned rights, namely, representatives of government departments, private sector developers, financing institutions, and civil society formations. My main findings are that few actors in the configuration support the view that the Constitution should be changed to make explicit the state’s obligations on the realisation of social and economic rights. Nevertheless, there are isolated cases of people expressing an absolute entitlement sense of rights --- the state should deliver when demands are made. My conclusions are that considerable political unrest about non-realisation of these rights will persist, but will not cause a collapse of the post-1994 political institutions and processes. More likely, political actors, legal scholars and jurists, will persistently engage the prevailing rights discourse and the variety of institutions acting towards their realisation, without effecting drastic changes to these, but always invoking positions about how they still are suited for a post-apartheid transformation project yet need critical interrogation and improvisation.
